Phys Rev Lett. 2005 Nov 11;95(20):200503. doi: 10.1103/PhysRevLett.95.200503. Epub 2005 Nov 9.

Abstract

We define the algorithmic complexity of a quantum state relative to a given precision parameter, and give upper bounds for various examples of states. We also establish a connection between the entanglement of a quantum state and its algorithmic complexity.
